TROLLEY.

SPECIFICATION forming part of Letters Patent No. 678,143, dated July 9, 1901.l

Application filed September 8, 1900. Serial No. 29,432. (No model.)

To @ZZ whom t mer/g1] concern,.-

Beit known that I, FRED'R. TAISEY, of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Trolley; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the ace companying drawings, in which like numerals refer to like parts.

The chief feature of the invention consists in pivoting a trolley-carrying arm and a guarding fork or lever on a suitable support, so that they will be vertically movable, and connecting them, so that the vertical Inovement of one will cause the vertical movement of the other at a different speed. The object of this feature of the invention is to prevent t-he trolley from escaping from the wire. The instant the trolley starts to leave the wire the guarding-fork moves upward much more rapidly. This feature of the invention is carried out here more specifically by pivoting the trolley-carrying arm away from its end and providing a spring which tends to elevate the trolley end and depress the other end of the,` arm. The guarding-fork is pivoted to the saine support much nearer Aits end than the arm, and a linkbar connects the ends ot' the arm and guarding-fork,so that any down wardl movement of the innerend oi the arm would cause the elevation of the guarding-fork more rapidly than the trolley. As here shown, the guarding-fork would move upward three times as fast, so that the trolley could not make any appreciable movement upward away from the wire until the fork would be elevated above the wire, thus preventing the escape of the trolley.

The full nature of my invention will be understood from the accompanying drawings and the description following of one form of device embodying said invention, and the scope of said invention will be understood from the claims following said description.

In the drawings, Figure l is a side elevation of the device with the parts in section, as shown, and the trolley-pole partly broken away. Fig. 2 is a plan of the same, parts being in horizontal section, as shown, and the trolley-pole shown in dotted lines to one side. Fig. 3 is a side elevation of a portion ot the device, showing the guarding-fork elevated.

V5 and the support 6.

l In detail, l represents the conducting-wire, and 2 the trolley-pole, which, as is understood by all, is'usually connected with the top of an electric car and extends upwardat an inclination rearward. Enlargement of the upper end of the tolley-pole is effected by securing the casting 3 to the pole. It is horizontally recessed at Ltto receive the extension 5 of the support or frame 6. The pivot-pin ".7, which is held stationary by the screw 20, y extends vertically through a suitable hole in said extension 'and the portions ofthecasting 3 that lie above and below the extension In other words, the mounting of the support 6 is such as to render -it horizontally movable or oscillatory.k It is held normally in alinement with the pole by the dat spring 8, that rests against the pivot-pin 7 at a point where said pin is flattened on two opposite sides, as appears in Fig. l and by dotted lines in Fig. 2, to form recesses 22 in said pin. The spring is prof vided with two parallel arms which bear against ,the flat sidesof the recessed portion ingL made at 9 in the extension of the support and bear laterally against the inner surfaces of the two sides of the support 6, as appears in Fig. 2. Said spring is held in horivzontal position by the opening 9, through I. of the pivot-pin and extend through an openy The trolley-carrying arm l0 is pivoted to the Asupport 6 by the pin ll at a point away from its end. A spring-wire 12 is coiled about the hub 13 on the trolley-carrying arm. One end (the left-hand end 'as appears in the drawings) of said wire is turned outward and enters horizontal holes at 21 inthe twosides of the sup port The other end is looped across the inner end of the trolley-carrying arm 10, as appears in Figs. l and 2. The tendency of this spring is to throw the outer end ofthe trolley-carrying arm upward and the inner end downward. The outer end of said arm will be usually held down by the wire 1, it acting on the trolley 14, that is pivoted between the two branches 15 of said arm. r

The guarding-fork 16 is pivoted to the sup- Ico port 6 by the pin 17 at a point nearer its end than the pivot-pin 11 is to the end of the arm 10. As here shown, the distance between the end of the arm 10 and its pivot-pin is about three times greater than the distance between the end of guarding-fork 16 and its pin 17. A link-bar 1S pivotally connects the ends of said arm 10 and guarding fork 16. Said guarding-fork is curved downwardly Somewhat for a portion of its length and then turned upward and bifurcated, with one prong of the fork extending on each side of the trolley, but both extending between the branches 15 of the trolley-carrying arm 10, as appears in Fig. 2. The outer end of said fork turns down ward over the end of the arm carrying the trolley and rests normally on the end of said arm. The prongs or branches of said guarding-fork are widened on their upper sides at the upward curve about the end of the trolley-support at 19, as shown in Fig. 2, to furnish additional means for preventingthe escape of the trolley by mere lateral movement thereof.

From the foregoing description it is seen that the action ot this trolley-guard is automatic. It the trolley escapes from the wire and starts upward, the end of the guardingfork will swing upward at three times the speed of the trolley. In fact, by the time the trolleypole is depressed en ough to let the side flanges of the trolley escape from the wire the guarding-fork is elevated above the wire.

Trolleys usually escape bythe downward movement of the upper end of the trolleypole, and such downward movement of the upper end ot' the trolley-pole has the same:

effect by way of elevating the guarding-fork as the upward movement of the trolley, as it lowers the inner end of the trolley-carrying arm, and any movement of either trolley or pole which will lower the inner end of the trolley-carrying arm will throw the guardingfork upward at about three times the speed of the trolley or the upper end of the trolleypole. The upward position of the guardingfork is illustrated by Fig. 3.

That I claim as my invention, and desire to secure by Letters Patent, is

l. The combination with a trolley-pole, of a vertically-movable trolley-carrying arm, a vertically-movable guarding-fork, means for supporting them, and a connection between said arm and guarding fork whereby one while vertically moving will vertically move the other at a different speed.

2. The combination with a trolley-pole, of a support, a trolley-carrying arm and guardin g-fork both fulcrumed to said support away from their ends, the fulcrum of said guarding-fork being farther from its end than the fulcrum of the arm is from the end of the arm, means for moving one of said members vertically, and a bar pivotally connecting the ends thereoff 3. The combination with a trolley-pole, of a support, a trolley-carrying arm fulerumed to said support away from its end, said arm having a hub at its fulcrum, a spring coiled about said hub with one end secured in the support and the other end of the spring acting on the arm to elevate the outer end thereof, a guarding-fork with its prongs normally resting on each side of the trolley, said fork being fulcrumed to said support at a point nearer its end than the fulcrum of said arm is to the end of the arm, and a bar pivotally connecting the ends of said arm and guarding-fork.

4:. The combination with a trolley-pole, of a casting secured to the upper end thereof with its end horizontally recessed, a vertical pivot-pin mounted in said casting and extending through said recess, said pin having at one point oppositely-attened sides, a trolley-carrying arm, a support, two Vertical sides between which said trolley-arm is secured, and a fiat spring that surrounds the flattened portion `of the pivot-pin with its free ends pressing against the sides ot said support.

5. The combination with a trolley-pole, of a horizontally-movable casting or extension pivoted thereto, a vertically-movable trolleycarrying arm mounted on said casting or extension, a vertically-movable guarding-fork also mounted on said casting or extension, and a connection between said trolley-carrying arm and guarding-fork whereby one while vertically moving will freely move the other at a different speed.

In witness whereof I have hereunto affixed my signature in the presence of the witnesses herein named.
